We have a program with two streams (English and Spanish) with Transition Rules to switch if they change language preferences. The content only varies by language. I've just learned that we may have a new "category of people" now - who will receive the exact same content EXCEPT we will refer to them in the emails as something like "members" vs "supporters". We will use a combination of lead source and other factors to determine this difference - there is no SFDC or Marketo field that indicates it clearly.
Question: is there a way to use something like tokens so that instead of two copies of all the English emails, I can define something like: for Stream 1 use saluation X, for Stream 2, use saluation Y? Any other ideas?
